I recently purchased a 75 CB 750 and I need to replace the spark plug wires because they are all mangled and destroyed at the lower ends. However, they seem to be run right into the coils with no connectors. Is there any way to get them off or will I have to replace the coil and spark plugs together? I'd rather not replace the coil if I can avoid it. Thanks

this is a dilemma I have at moment with my coils.
I intend at some time to repair by cutting off HT leads flush with coil, push in a Brass pin and attach new HT lead to exposed part of pin, then seal with an epoxy resin.
You could also use a Silicon Sealer, just thought the epoxy resin would offer more support.

would that weaken the spark or anything?

malcolmgb · « **Reply #3 on:** January 03, 2007, 03:19:34 PM »

shouldn't do, use the same length and type of HT lead, the brass pin should not cause a high resistance or corrode unduly. There is a thread somewhere on here about similar repairs.

No such thing as a stupid question on this forum. Some of the answers we give might be a bit questionable, though!!

jakethesnake · « **Reply #7 on:** January 03, 2007, 03:51:06 PM »

so is that the only advisable answer to my question? i'm not sure i trust my epoxy resin skills that much...

Jake, Check Parts N More, I think they carry an NGK splicer.

I dunno about stupid questions. I remember a thread of mine that was rather stupid.

I've used those wire splicers from Z1. Great success.

Hey Snake...
I wrote up a how to on replacing the wires about 6 months ago...with some picts...so far it's worked great...I've put about 5,000 miles on them so far.
Takes about an hour or so and some simple surgery of the coils...
Can't remember the thread...but you should be able to search for it...

jakethesnake · « **Reply #16 on:** January 04, 2007, 08:26:14 AM »

so how exactly does it work? or is it pretty self explanatory once i get it?

hcritz · « **Reply #17 on:** January 04, 2007, 08:28:51 AM »

Should be...I used a dremel tool and cutoff wheel and cut the plastic of the coil at the wires...Soldered new ones in and filled the cut out area with epoxy....
Brand new wires all the way to the coil...
I'll see if I can find the like to the post.

Hey Jake...
Here is the link...

I had a hard time getting the picts small enough to post...most of the info is on page 2 and there is a link to the picts...hope they are still there...
I "MAY" still have the doc. somewhere on my computer if the picts are gone.

Another option is replace the coils with a set for an early 1980's CB900. I believe mine were from a 1981 model. Many of our members here have done the same upgrade. I found a set on ebay for less than $15. These will give you a hotter spark, allows the option of changing the wires (as the wires are not permanently attached). On my 1978 CB550K, I only had to reverse the mounting bracket...no other mods needed. Down side is a hotter sparks may burn out the points sooner than the original coil might. It changes it from a 5 ohm to a 3.3 ohm. I did mine over 2 yrs ago and have not had a problem yet.

Later, if you want to upgrade to an electronic ignition....these coils will handle that fine. Hope this adds some insight. DrMark

i just pulled the old ones out and twisted new ones into the coil and to the spark plug caps.
make sure you get solid core wire.

dusterdude · « **Reply #21 on:** January 04, 2007, 10:27:25 AM »

my local honda dealer sells the ngk splicers too.

jakethesnake · « **Reply #22 on:** January 04, 2007, 01:04:45 PM »

how do i use the ngk splicer? does it splice it to part of the old lead or directly to the coil because one of the old leads is also pretty mangled where it goes into the coil so i can't splice the two leads together

NGK 7mm Sparkplug Cable Splicer

Description: For those using a sealed CDI system, NGK has developed a water resistant cable splicer to connect NGK Racing Cables to the stock ignition system. Simply insert each cable into the splicer, tighten, and you are ready to go. When used in conjunction with the NGK Cable Splicer, NGK Racing Cables can save you the significant expense of replacing entire ignition systems simply because of a failed cable.

worked for me but i cut mine off out from the coil, not directly off of it so I'm not sure, i think you can get the coil open and rewire a new wire to it, at least i think i read about doing that somewhere

Yeah, what he said! lol I picked up coils that I think were from a Honda NightHawk, originally? They have like an NGK splicer thingy built into the ends of the coils for wire replacement. (see picture)
